Pier position in dome

[Helo]

OK - I have my pier design sorted now (previous post, steel vs. concrete pier) but as I am fixing a wedge on top this throws the telescope axis off the pier centre. I need to centre the scope in a dome to be constructed so what do I use as the 'centre' of the dome; 1) the new mount position of the base of the scope to the wedge or 2) the position where the fork arm attaches to the scope? :question: I believe it is 1) (the join to the wedge), but also where is the centre of mass of the scope (CPC 1100) and should I then offset the wedge to counteract this and centre it over the pier? Thanks for any help IIS members can offer.

Make the Dec axis the centre of the dome.
So the scope will be taking up space in the north area.
Then you dont need to calculate any numbers to offsett the dome slit.

So when the scope points directly up, it also points to the centre of the dome (Downwards).

Dont worry about balancing, as long as you bolt it down, it wont go anywhere.

Thanks Rally and Theo for your help. I can't wait to get it all started now and get in the dome. :)
